Tou/t whom it 11i/cy conce/a.

Bc itknown that I, HANS THORMEYER, a subject of the King,` of Prussia, Emperor of Germany, residingfat llingartesmiihle, near 5 Hersfeld, liesse, (nlermany,` have invented a new and useful Rotary Si earn 'lnginepf which the following is a specifiiation.

My invention relates lo improvements in rotatory steam-engines in which the presio sure-spacesare formed in suchamannerthat the'slide-wings oler the entering steam a largerisurface than in devices hitherto made and in which thc slide-wings after closing the entrance-port through which the steam l5 enters are pushed faiithcr outward toward the penlphery, so as to offer astill larger surface for better utilizing the expansion of the steam. ln the accompanying drawings, l-igure 1 2f shows in section a side elevation of my improved-engint-g and l"ig. i is an end elevation thereof, also in \'crtical section.

l'tel'errii to he drawings, in an annular 'asing n, e ed :it both sides by the covers .f o; end pieces is revolublymounted a Shaft d, on which is secured the disk il, carrying the slide-wings .f. These wings are pressed outward by a spirallspring or the like against theouter wall ol the casing, so as 'to follow 3o the l'orm of the pressure-spaces f. Those parts of the spaces l(orsteamways) which are under high pressure4 and in which the filling takes place are parallel with the outer surface qfvthelxdisk il. l

It w'll be seen that from the inlet-portaA to the point-.jy there will be no outward movement of thewings c, as the chamber remains the same in size. ,'lhe moment the wing real-hes r/ the steam is automatically cut ollf yflihs'rnnfr Fines.

manlief/34.155.411@ matti from i, and as itcontinues to expand as the Jhamber f enlarges so does the surface of tlie wings e acted on by such expanding steam also enlarge. The outlet-ports connecting the steam-chamber with the exhaust are of large size comparatively, as is also the passage l; itself, whereby almost instantaneous clearance of the exhaust-steam is had and back pressure previ'fnted.

What I claim as new7 and desire to secure by Letters Patent, is-

In a rotary steam-engine, the combination with acasing forming an inf'losed chamber, of a disk or drum, revolublymounted in such chamber, and carrying slide-wings e, means for keeping the slide-wings c pressed out- Ward against the wall el. the chamber.y two inlet-portsi, i', a steam-passage leading to each of said ports i, a valvelocated in each of said passages, an exhaustoutlet port adjacent to each of the inletports, the wallspaces from the outlets to the next inlet abutting against the periphery of the disk or drum, so as to leave no steam-space, and steam-spaces between the drum and casing extending from each of the inlet-ports tothe next exhaust-port having the lirst port-ion from t' to y of the same sizethroughout, and

the portion from q to thenext exhaust-port Ilrst gradually enlargedfand then gradually contracted, substantially as shown and described. f.

In witness whereof .-,have hereunto set my hand in presence of/two witnesses.
